I feel like you'd need a new corporate structure or something, like the way an S-corp is different, but on steroids.

Because I agree, the forced obsession with "growth" at all costs, which seems necessary to operate a public company (at least in this century[1]), is imho the #1 reason why enshittification is unavoidable.

[1] I'd describe nearly all present-day corporations as fixated on quarterly results even at the expense of business viability. Something I truly don't understand is why big companies say, 75 years ago seem to have been so much less that way. If anyone has any theories I'd love to hear them.
